Eucalyptus

Wood produced in our factory in Neiva- Viana do Castelo Portugal
Tree of the Myrtaceae family, eucalyptus is native to Oceania, where it is the dominant species of the local flora. With more than 700 species, the majority of Australian origin, it adapts to practically all weather conditions. Its crown has persistent foliage, whose leaves are covered by glands that secrete oil and, when young, are opposite, between rounded and oval. With one or two years of growth, these leaves start to present a new shape, alternating between lanceolate and falciform, narrow and drooping from long and newly emerged petioles, this occurs in most species of eucalyptus. A curious fact related to eucalyptus foliage is that, until mature leaves appear, these trees will not flower.
The first botanical description of the genus was the responsibility of the French botanist Charles Louis L'Héritier de Brutelle, in 1788. The name of its genus, which could be translated from Greek as "good cover" refers to the cape or operculum that covers the organs flower reproducers, until it falls and leaves them uncovered. This operculum is formed by modified petals. In fact, the attractive power of its flower is due to the exuberant collection of stamens that each one presents, and not to the petals, as happens with many plants. The fruits are woody, vaguely conical in shape, containing valves that open to release the seeds.
The suber, or bark of the tree, has an annual permanence cycle, and the various species of eucalyptus can be grouped according to their appearance. On trees with smooth bark, virtually all the bark falls off, leaving a flat textured surface, sometimes stained with various colors. In rough-barked trees, the rhytidome persists clinging to the stem as it slowly dries. Many trees, however, show differentiation at this level, with smooth bark at the top and rough bark at the base of the trunk. Among the rough-barked trees, we can distinguish:
• Split shell - which has long fibers that can stand out in long pieces. It has a thick rhytidome with a spongy texture.
• Hard-shelled - rough in appearance and deeply cracked, its rhytidome is usually saturated with a resin exuded by the plant, which gives it a dark red or even black color.
• Tessellated - with the shell fragmented into distinct flakes, forming a mosaic. The fragments, which fall over time, are similar to cork.
• In a safe - composed of short fibers. Introducing, some, tessellation.
• Striped - in which the bark comes out in long, narrow pieces, although adherent to certain parts of the stem. They can appear in the form of long bands, strong ribbons or curling pieces.
